Well I would like to see a Constitutional Amendment that limits Federal ownership of lands within a state to no more than 20% of the total land mass.
Well here’s the thing the Enclave clause of the Constitution directly addresses the govt ownership of land says that the govt can own and use public land in the states for the purpose of forts, armories, magazines and other needful buildings. That’s it end of reasons.
The US govt does not have a specific right to commandeer millions of acres of land in the states. They certainly have no right to take and hold it for oil leases, tortoises, grazing fees or even just keeping it as a wilderness area. The states need to stand up and take back their property. We don’t need to amend the Constitution. We just need to force the US govt to abide by it.
No need. It is already there - "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
The Constitution says nothing about the Federal government owning or controlling land. Another amendment won't do any good with a regime that ignores The Constitution anyway.
